object value;
Parser.TryParse(typeof(int), "1", out value);
is a valid call to the second (non-generic method).
It would seem to me that it is then inferring T as object here ...
return TryParse(input, out value);
because if
public static bool TryParse<T>(string input, out T value) value is
an object ... (and its a T) T must be an object.
What were you expecting to be the error and why?
Cheers,
Greg
